      The chainset and the front mech is different, too.
      And upgrading from 105 7000 isn't worth it. The clutch isn't a game change imo.

    I’ve got this group set on my new Reilly. It’s pretty good, the hoods are very comfy and give much better grip. Only issue is the rubberised lever finish, it’s not very robust and scratches really easily, which makes them look tatty pretty quick.

      Echoing Erwin Sikkens here, I've recently ridden the Topstone Carbon with Ultegra RX and an All-City Cosmic Stallion GRX, and the slip-reducing coating, while you can scratch it off a little too easily, is much much better than the glossy and slippery Ultegra levers. The grippier levers combined with the raised pivot point create a vastly improved breaking experience, trust...

    The stupidly high amount of setup options available for this groupset are phenomenal. They've really managed to make this line a relevant and marketable product. I could see elements of this appearing on both my out and out race bike as easily as they could be found on my touring mtb. Those Di2 shifters with non linear pull and options for inline hydro are a total game changer.

    2020 trek dual sport 4 hybrid bikes use the same gearing as your test bike. We threw on some 35c tires from the standard 38c for a bit better on road performance but still keeping that gravel ability. Gravel is here to stay. I'm glad because we have more gravel paths than tarmac paths. Wouldnt mind drop bar option on the dual sport 4 though.

And now that i will make a 3 day bikepacking across some Algarve mountainous backcountry (its almost like a roller coster), and since IÂŽm on the heavy side, just changed my rear cassete to a 11-40 Slx and just put an extender om my 105 rear mech, and its working fine till now ( crankset is a Praxis Alba 48-32).

    -Raised pivot is only in Di2 levers, not mechanical ones
    -That rear derailleur is the RX812 for 1x11. The RX810 is the 2x11 option and is really similar to the Ultegra RX800
    -The top of the range gravel groupset is the RX810, not RX800, because RX800 is Ultegra RX
    -The RX812 RD only can fit a 11-32 or 11-34 cassette as the smallest one (in the biggest cassette 42t easily and even 46t confirmed by me). I use it with 11-34 for cx and with the tension screw almost completely unscrewed to get a proper distance between upper pulley wheel and the 34t sprocket

    I have recently installed a grx fc-rx400 46/30 2x crankset on a bikenstein build that has sora r3000 shifters and front mech. By unwinding the outer limit screw, and properly tensioning the front mech cable, I could get them to work together flawlessly. Shifting is spot on, and I get no derailleur rub. Front trim is somewhat limited though, but it’s nothing unbearable.

    I built a bike around a bombtrack frame and a mix of grx compontents. 600 shifters & 2x crankset, 800 derailleurs and 400 brakes with ultegra rotors. So far I have ridden it for 200kms and the performance is very good! Better shifting than my 105 5800 on my road bike. Brakes are unbelievable as you'd expect from hydraulic brakes.
    Some things to note: The 800 series shifters offer a feature where you can adjust the stroke of the brake lever and the different pivot point is only availbale for di2. Dont try to mix 2x on the front with 1x components in the rear. The articulation of the rear derailleur is different and there is not enough tention on the chain. I would try a wolftooth extender for the 2x rear mech to make it for more gears for uses like touring where you need some extra low gears.

    I think you mostly missed that now there are chain rings that go smaller than a compact crank will accept with it's 110 BCD limitation of 34t. One by for gravel is silly and subcompact makes much more sense to get both the needed range for a low 30 x 34 combo and not too much penalty with 48 x11 top gear for the flats and down. This is the benefit of GRX. One by, you could just go with SRAM, if you don't mind the crappy brakes and Dot whatever brake fluid. Did not know the lever re-design particulars, thanks.

    Thanks for the video. I was actually very excited about this groupset, since I'm building a gravel bike. But there are some underwhelming points:
    0) discs are only hydraulic and I just hate that, because, while it's true offer have better modulation, they are still difficult to set up and if something happens in the field, it's game over. And this all comes at double the price of a mechanical set of very good mechanical discs.
    1) The RX800 long rear derailleur, aside from suspiciously looking like a Deore XT piece with GRX written on it and (maybe?) different cable pulls, it's stupidly expensive compared to the XT and SLX homologous, even if you count the cable pull converter. I did not yet see anywhere an RX600 RD, and the big fat RX800 is the only one that can go up to an 11-42 cassette.
    I'm a big Shimano fan, but the GRX doesn't do it for me: I went for 105 STIs and FD with an adapted SLX, 11-42 cassette and a double 46-36 chainset at the front. Shimano's mechanical calipers onto Shimano discs. All in exquisite silverâ˜ș.
    P.S.: those bits are for sale since a while now... With prices. When did you record this video?

      Actually don't be afraid of hydraulic brakes. I've ride them very abusive on mtb- and also on long brevets 400-600km.
      They don't fail.
      Regarding rear derailleur, I'm using 105 medium and it works fine with 40 cassette. But you can add an adaptor it's 5usd on ali. if it's not enough.
      Not sure about the price of Ultegra with clutch derailleur.
      Guess the main gain here is the brakes leavers.

      Oleg Revulet That's good to hear. I also have them on my MTB but not since long. I must say I didn't really enjoy setting them up with the mineral oil and stuff... And, also, the levers I have don't offer that much adjustment (but I guess this depends on the specific model). One big difference between MTB and road hydraulic discs is the price: hydraulic STIs are still exactly twice the price of mechanical ones. And usually bigger... Yes, I agree that the main point of the GRX may very well be the top levers (still eye-watering expensive compared to their mechanical counterpart).
      It's very interesting what you say about the 105 RD, which I guess extends to the Ultegra RX. I went for the SLX because I was after a RD with a clutch and, with the Jtek adapter, came away at around the same price of the Ultegra RX while not requiring an extender, and was still cheaper than the GRX810 --an XT plus adapter would have costed the same but, as you might have already sensed, budget was a very big consideration with this bike.

I find I'm rarely spun out on in my 50/11 combo on my road bike, so I'm not too concerned about being limited to a 48/11. And having the freedom to go to 31/42 on 650b wheels, there shouldn't be many trails I can't take on that are short of rock crawling.

    There should be switch for lights also integrated on levers.. Because it's adventurer bike, you need to change light settings from hi beam to low beam or intensity of light, but sometime you can't take hand off from handlebar to do that. In snow or mud or sand or something and then you have no choice but to dazzle all oncoming traffic because you just can't, without stopping at least.. but then it can be challenging to restart once you have stopped on bad road.

    In future videos it would interesting to explore how you can upgrade/ simple hacks with GRX components into exisitng groupsets if you are on a budget. For example can you upgrade the chainrings from an existing Tiagra 50/34 to a GRX400 46/30 easily - or do you end up needing to change the FD, RD, chain and BB as well? Then you might as well add in the shifters!! Then up mights as welll upgrade to the 11 speed GRX600 - one of the kids is going to have to drop out of university so I can pay for this!!

      I've tried that already and I can tell you that you could do what you asked about if the bracket for the front mech installation allows the mech to move down to accommodate smaller chainrings. In my case I changed from 50-34 to 48-32 and the bracket on my carbon frame did not allow the mech to move down enough for a crisp gear change. Because the bracket was fixed in the frame I had to remove some material from the lower part of my bracket so that the mech would slide to a lower position (about 1mm lower). Wasn't the most elegant solution but that made shifting very good. if you have an alloy frame you could have the bracket installed with a collar which will allow you to move it wherever you feel. Carbon frames tend to come with brackets installed in carbon and moving them is impossible without a major carbon operation which is very dangerous for the frame.

  • @Piplodocus
    @Piplodocus Pƙed 4 lety +2

    As a GRX owner that came on my gravel bike (Whyte Gisburn v2), here's my thoughts...
    I like 1x (I have SRAM Eagle 1x12 on my MTB). I love the GRX feel. I love having a dropper post as the left lever paddle. I like the brakes. I like the idea I can add the in-line mini sub-brake levers down the line as an upgrade. So I'd take GRX over SRAM for gravel. With a 38t chainring (it came with Easton cranks and 38t ring) it's fine for off-road stony hills and I wouldn't like much bigger a chainring else if I've got bikepacking luggage, or if I just wanna go up extra steep stuff, I wouldn't be so happy getting up there. But the 11t with the 38t combo can get a little spinny on smooth tarmac or downhill. So I just fitted an XD driver and SRAM 10-42t cassette. That extra 10t makes all the difference. I love it and it now seems perfect for what I want it to do. So I think where Shimano “got it wrong” with their 1x IMHO, is for the best balance it needs a standard 38t chainring available and (I guess with their microspline freehub) a 10-42t. 11-42 is fractionally too slow in the top with a 38t for my liking, but would undermine the climbs with a bigger front ring and the 11-42. Else keep the bigger chainring and have more teeth on the low end of the cassette to give the wider range. Obviously this is personal and depends on terrain and your legs, but for me, using it as a regular commute mostly on tarmac, and adventure bike all over the place in some pretty gnarly off-road places (and the fun bits of the commute), 1x systems with 420% cassette range just plain make more sense than 380% range.
